EDGE-SETTER.

. SPECIFICATION forming part of Letters Patent No. 575,531, dated J'anuary 19, 1897.

Application filed April 17, 1896.

T0 @ZZ whom, it may concern:

Be it known that I, CLAY M. NEWCOMB, of Rochester, in the county ofMonroe and State of New York, have invented certain new and usefulImprovements in Edge-Setters; and I do hereby declare the following tobe a full, clear, and exact description of the same, reference being hadto the accompanying drawings, forming a part of this specification, andto the reference-letters marked thereon.

My present invention has for its object to provide an improved burnisheror edge-setting machine of the class in which the iron is capable of.rapid vibration; and it consists in certain improvements in constructionand combinations of parts, all as will be hereinafter fully described,and the novel features pointed out particularly in the claims at the endof this specication.

In the accompanying drawings, Figure lis a side elevation of a portionof a machine constructed in accordance with my invention; Fig. 2, afront view of the same; Fig. 3, a sectional view on the line x :r ofFig. l; Fig. 4, a sectional view on the line y y of Fig. 2 Fig. 5, asection showing the tool-attachin g spring.

Similar reference-letters in the several figures indicate similar parts.

A indicates a standard of any suitable construction, having at its upperend a frame B, provided with suitable bearings for a shaft C, providedwith a belt-pulley D, adapted to be driven by a suitable driving-belt.

C indicates crank-pins on the ends of the shaft C, and E pitmen orconnecting-rods journaled on said crank-pins at one end and v at theother connected to andy vibrating the arm carrying the edge-settingtool.

In the present embodiment of my invention I have provided for twovibratory arms G, on which the burnishing-tools are mounted, journaledloosely on opposite ends of a stationary shaft or arbor F, secured byset-screws j' to the frame I3, as shown in Fig. 2. Each of the arms G isprovided with the sleeve-like portion extending around the shaft, andits upper end is provided with a curved slot G, in which is adjustablysecured a block H, having a wrist-pin II', upon which the outer end ofthe connecting-rod E is journaled, said block being adjustable in theslot G to permit variations in the throw of the vibratory Serial No.587,960. (No model.)

arm. The lower end of the arm is provided with a longitudinal recess.preferably inclined relatively to the plane of the upper portion of thearm, and in this recess is arranged a sleeve J, to which is secured apin J', passing out througha slot G2 at one side, and sliding upon thispin is a sleeve j, cut away at the sides, so that the inner ends thusformed may engage suitable notches ls, formed in the flanges k' onopposite sides of the slot G2.

m indicates a spring encircling the pin J and arranged between the headof the sleeve j and a small washer m', removably secured to the end ofthe pin J', which spring operates to hold the engaging portions of thesleeve y' in engagement with the notches 7c, thereby locking the sleeveJ and preventing its rotation relative to the vibratory carrier.

K indicates a spindle operating through the sleeve J, having at itsupper end a small pin K', operating in a vertical slot K2 in the upperend of the sleeve J.

M is a ring or collar held against a transverse pin n in the lower endof the spindle K by means of a spring N, encircling said spindle andarranged between the sleeve J and the collar M, as in Fig. 3.

O indicates a double edgesetter or burnishing-tool having two operativefaces o projecting in the present construction at an angle to eachother, as shown, said tool being provided with a socket to lit over theend of the spindle K and is held in position thereon by means of aspring-catch P, as shown in Fig. 5, the upper sleeved portion of thetool having slight recesses engaging the pin n and preventing rotarymovement on the spindle.

It will be understood that tools having more than two faces may beemployed, if desired.

Mounted upon the standard A are the usual gas-burners A' and thefinger-hooks A2, the flame from said burners operating to heat the toolproperly, while the hooks serve their usual purpose of enabling theoperator to ,steady the shoe being operated upon.

By the employment of the double tool,the edge-setting faces beingarranged close together, as shown, both of said faces are heated at thesame time, and the operator may bring one or the other of them intooperative posi- ICO itwhen reversed by the sleeve, as will be understoodfrom an inspection of Figs. 3 and 4. The tool is held in engagement withthe shoe by the pressure of the spring N, surrounding the spindle, andthe latter is permitted to yield slightly by reason of the slot-and-pinconnection of its upper end with the sleeve J.

By making the slot in the upper end of the vibratory tool-carrying armcurved, as shown, said curve being approximately on an are struck fromthe center of the drivinmshaft C, the latitude of movement of the armcan be changed without causing the center of the are described by thetool to vary from just over the linger-hook.

I clailn as my inventionl. In an edge-setting machine, the combinationwith the vibratory arm having the lon gitndinal recess, the rotarysleeve, and means for locking it, the spindle longitudinally movable inthe sleeve but prevented from independent rotary movement, the springpro jecting the spindle, and the reversible tool on the spindle,substantially as described.

2. In an edge-setter, the combination with the vibratory arm having thelongitudinal recess, the rotary sleeve, and locking devices therefor, ofthe spindle, the tool thereon, the slot-and-pin connection between thesleeve and spindle, and the spring for projecting the latter,substantially as described.

3. The combination with the vibratory arm having the longitudinal recessand lateral slot, the sleeve having the projecting arm and the lockingdevice thereon, the spindle and the slot-and-pin connection between itand the sleeve, the collar M on the spindle, the spring N, the catch onthe spindle, and the reversible tool having two operating-faces and heldby the catch, substantially as described.
